Iridium catalysed C−H borylation provides an effective method for late stage functionalization of fluorinated arenes and heteroarenes. The reaction occurs rapidly and efficiently with selectivity that can be best predicted using computed relative transition stage energies.

An efficient one-pot C-H activation/borylation/oxidation protocol for the preparation of phenols is described. This method is particularly attractive for the generation of meta-substituted phenols bearing ortho-/para-directing groups, as such substrates are difficult to access by other phenol syntheses.
